Bastarnae Mercenaries. I wasn't expecting much out of them when I hired them. I just needed some fodder for a siege. They were the first to go throught the breach in wall A where most of the enemy was, and Then I focused on getting my legionaries through the breach in Wall B. When that was done, the Mercs were still happily fighting away! One unit of them finally broke when the fight was at the city square, but I don't blame them as they had 8 or 9 men left. Then I noticed after the battle they have 2 HP, fast movement, great attack, and the same size as an average unit of legionaries.

Now I snatch them up whenever I can. In my armies that have them, my legionaries tie up the battle line, the Bastarnae Mercenaries hit the flanks, while the cavalry is snuck around and hits the rear of the flanks or runs down archers. Talk about chain routing...
